I had the same problem with dead links and they responded quickly. They are very nice. A long time ago they even gave me the source for their XFunction library after signing an NDA, which made things much easier to integrate.

Watch out whoever's buying it, this is version 8 they're giving out, which doesn't support Java 7. You have to pay $50 minimum per OS to upgrade to version 9 in January, which will have Java 7 support and no Java 6 support.
